Fujifilm Warns macOS Users of Firmware Incompatibilities

pcmag.com:

Fujifilm has warned its customers that a firmware issue can prevent them from viewing images on macOS—but only if they have more than 4,000 files in a single folder on an SDXC card.

The company says the flaw is found in a dozen X and GFX series cameras. Nine of them—the GFX100, GFX100S, GFX50S II, X-Pro3, X-T4, X-S10, X-E4, X-T30 II, and X100V—are affected regardless of their firmware version. The GFX50S, GFX50R, and X-T3 cameras are only affected by the problem if they're running specific versions of their respective firmware.

Fujifilm says the underlying issue results from the X and GFX series camera firmware allowing the devices to store up to 9,999 frames in a single folder. (Each frame, according to the company, can create up to three files depending on how the user is storing their photos.) But macOS only seems to be capable of handling about 4,000 files in a single folder.

This incompatibility can reportedly lead to a couple of problems. The first: "Some files on the memory card may become inaccessible if the card has been connected to the computer through an internal or external memory card reader and directly accessed using macOS." That's straightforward enough, but the second problem is a little more complicated. Fujifilm says:

If the memory card is not ejected correctly from a computer using macOS, there is a likelihood that data may be lost if the same card is directly connected and accessed a second time using macOS. However, risk of data loss in this situation can be prevented by following proper ejection procedures for macOS operating systems. If the proper procedures are followed, no data will be lost. However, files will still remain inaccessible when attempting to directly access the data on the memory
